9 Claims. (Cl. 70-86) This invention relates to cabinet locks and moreparticularly to a cabinet lock that is adapted for universal mounting indrawers or doors of varying thickness. in addition, our inventioncontributes a cabinet lock that may be readily inserted into the jambfor locking a door or into a cabinet for locking a drawer.

Cabinet locks of the prior art are usually equipped with a main casingportion and an extending nose, the lateral distance from the front ofthe nose to the rear of the casing being approximately the same lengthas the thickness of the door or drawer into which the cabinet lock is tobe assembled. Where surface applied, the nose is as long as thethickness of the door or drawer. Because of the particular constructionthe noses of locks of the particular class are supplied in diflferentlengths in order to fit dilferent drawers, and a lock of the particularclass is well illustrated in Patent No. 1,584,992.

Our invention, through a particular arrangement of the parts thereof,makes it possible to assemble a simple locking assembly into a drawer ordoor of any thickness, and makes it possible to insert our lockingmechanism readily into a relatively thick jamb or cabinet body, all aswill be clear to those skilled in the art.

As a feature of our invention we utilize a. locking cylinder that isadapted to be inserted into an opening formed in the face of the door orjamb, the cylinder being adapted for assembly to a bolt housing adaptedto be inserted in an opening in the edge of the door or the edge of thejamb as the case may be. Once mounted within the door, drawer or jamb,the two parts of our locking mechanism can readily be assembled and heldin operating relationship.

As a further detailed feature of our invention we utilize a simple screwthreaded assembly between the bolt housing and the cylinder that isadapted to be made after the cylinder and bolt housing are inserted intheir respective openings, thereby mounting the parts in assembledrelation and forming a complete lock assembly.

As a still further detailed feature of our invention the lock housingcomprises a front plate equipped for a pair of screws, one being a woodscrew, although a machine screw may be utilized where the lock isassembled to a metal door. Regardless, the particular screw engages andlocks the front plate to the member in which the lock is mounted. Theother screw is adapted to lock the bolt housing to the cylinder in itsopening, that opening being preferably at right angles to the firstopening.

A still further feature of our invention resides in the utilization of anovel form of cam operated by the key plug and coacting with the boltfor projecting or retracting the bolt.

As another feature of our invention we so construct our novel cabinetlock that it is adapted to be mounted in holes that are formed in thedoor or other structural member by boring, the lock cylinder beinginserted into a hole bored in the face of the structural member, and thebolt housing being inserted into a bore in the edge of the member. Anadditional bore is formed in the edge 2 ,7 Zll,lll Patented Oct. 11,1955 of the member to receive the screw that assembles the bolt housingto the cylinder, and the front plate of the lock preferably is so formedthat it will be mounted flush in a recess that is made in the edge ofthe structural member principally by boring.

We have thus outlined rather broadly the more important features of ourinvention in order that the detailed description thereof that followsmay be better understood, and in order that our contribution to the artmay be better appreciated. There are, of course, additional features ofour invention that will be described hereinafter and which will form thesubject of the claims appended hereto. Those skilled in the art willappreciate that the conception on which our disclosure is based mayreadily be utilized as a basis for the designing of other structures forcarrying out the several purposes of our invention. It is important,therefore, that the claims be regarded as including such equivalentconstructions as do not depart from the spirit and scope of ourinvention, in order to prevent the appropriation of our invention bythose skilled in the art.

Referring now to the drawings:

The preferred form of our novel cabinet lock that we have shown in thedrawings includes as the two principal parts of its assembly the lockcylinder 10 and the bolt housing 11, and for the purpose of providing aclear understanding of our invention I have shown these parts in theirinstalled relation in a member A. Certain openings are, of course,prepared to receive the lock in the member A, and these openings arearranged in a particular manner that will become apparent as thedescription proceeds.

In the cylinder 10 is a rotating key plug 12 and, for purposes ofdescription, we have chosen to illustrate a key plug of the type that iscontrolled by the position of key actuated tumblers 13 relatively togrooves 14 in the interior of the cylinder 10, although the specifictype of key plug that is used is not important to our invention. We do,however, mount a cam 16 upon the rear end of the key plug 12 by suitablemeans such as an oblong stud 15 to which the cam is staked, so that thecam rotates With the key plug and also retains the key plug in thecylinder. The cam 16 moves the bolt, as will be described, through anintegral arm portion 17 that extends toward the outer end of thecylinder 10 along the side of the cylinder. Because the cylinder 10 isto be installed with a nominal clearance in an opening B bored in thefront face of the member A, the arm portion 17 of the cam is locatedwithin the extreme diameter of the cylinder 10, and in order to allowmovement of the arm 17 in this position as the key plug 12 rotates, theside of the cylinder is formed with a recess 18. The ends of the recess18 form limits for the rotation of the arm 17 and preferably will allowthe arm a movement of about The side of the cylinder 10 opposite therecess 18 may be relieved, although preferably at least one projection19 is left at this side on the outer periphery of the cylinder to servewith other parts of the periphery as a guide to locate the cylinder 10in approximately its proper position when it is inserted into the boreB. A flange 20 on the outer end of the cylinder 10 will, of course,locate the cylinder in its proper longitudinal position in the bore B.

For assembly with the cylinder 10, the bolt housing 11 is adapted to beinserted in a bore C in the edge of the member A so as to occupy aparticular position offset at one side of the cylinder adjacent the arm17 of thecam. In this position of the housing, a fiat bolt 21 in thehousing is supported relatively to the arm 17 so that movement of thisarm projects and retracts the bolt. Actually, one edge of the flat bolt21 extends into the recess 13 of the cylinder 1'0 in ordertoengage thearm 17 of the cam, and this edge 'is formed with a slot 22 in which thearm 17 operates.

The means in our invention whereby thebolt housing 11 is assembled inits particular position relatively to the cylinder includes a part thatextends laterally from thehousing outwardly of the cylinder 10, andweprefer to utilize as this part one end 23 of a front plate 24. Offsetfrom the bolt housing 11 on the lower surface of the part "23 is anabutment 25. An opening is formed through the part 123 and the abutment'25 to receive a screw '26, and when this screw is engaged in a threadedbore in a medial portion or" the cylinder 10, the cylinder is drawnagainst the abutment 25 so that the housing '11 and cylinder 1'0 areassembled in their roper positions relatively to each other. Therecesses that are formed in the member A preferably include a recess Dthat affords the front plate '24 a ilush mounting in the edge of themember A, and do, of course, include a bore E extending inwardly fromthe bottom of the front plate recess D to receive the abutment 25.'Because a part of the member A is confinedbetween the cylinder 10 andthe part 23 of the front plate, the lock is quite securely mountedthrough the action of the screw 26 alone. We prefer, however, to securethat end of the front plate '24 which is opposite the end v23 directlyto the member A by a screw 27, but in any event the screws whereby ournovel cabinet lock is secured are inserted only at the edge of themember in which the lock is mounted. Also, because of the arrangementthat we have described, the bolt housing 11 is assembled always in oneparticular positionrelatively to the cylinder'lt) without regard to thethickness of the member A in which it is mounted, and therefore ournovel cabinet lock is universal in its application to members of-different thicknesses.

We have shown the bolt housing 11 in the preferred form of our inventionas including a pairof sections 28,

best seen in Figs. 4 and 5, that guide opposite faces .of

the fiat bolt 21, and that are integrally joined at their outer ends bythe front plate '24 and at .their inner ends by a bar '29. The housingsections 23 are ofapproximately the same width as the bolt 21 and do notoverlie the edges of the bolt, so that these sections themselves r donot account for any part of the diameter of the bore C in which thehousing 11 is mounted. .Parts of .the housing sections '28 are cut awayto avoid the recess 18 of the cylinder, thereby defining a diagonalopening 30 in the housing, and it is through this opening that the bolt21 extends so as to coact with the cam 17. The edges of the fiat bolt'21 are guided by the front .plate 24 and by the bar '29, a lowerportion of the edge of the bolt 21 being stepped inwardly to pass thebar 29 and also to provide a shoulder 31 whereby the bar serves as astop for the retracting movement of the bolt.

It is believed that the operation and the advantages of our novelcabinet lock will now be apparent from the foregoing description.
